In addition to Figure 6 is a view showing that side of these' guy ropes the mast is provided Vwith the bearing opposite to the one illustrated braces 26 securely bolted at their upper ends to the legs of the mast and diverging down- 29e in Figure 4.

- 1s in the form of a rod 46 suspended wardly away from said legs,the lower ends ofth'e braces heilig securely fastened to the beams l and 3. shaft 27 is journaled in suitable bearings supported by the lower portions of the braces 26 and this shaft carries the usual reel 28 and sand line pulley 29 that have been indicated only in a general way because they yare of the usual types.

Motion is adapted to be transmitted to the shaft 27 by chain 8 through a sprocket 30 and the usual clutch means may be employed whereby the several parts on the shaft can be operatively connected to or can be disconnected from the sprocket 30. Among those driven elements on shaft 27 Ais a sprocket. 31 adapted to drive a chain 32 whereby motion can be transmitted to a sprocket 33 carried by a shaft 34 which is journaled in bearings supported by the upper portions of the braces 26. This shaft 34 carries a secondary reel 35 likewise of` usual construction.

Secured within the mast at a suitable elevntion is a cross beam 36 to which is secured the base 37 on which is swiveled a yoke 38 shown particularly in Figure 8. This yoke constitutes the bearing of a pin 39 on which 1s mounted a walking beam 40. This beamI 'is formed of opposed spaced channeledv beams 41 connected at desired points by cross strips 42 and pivotal connection 43, with a pitman 44 adapted to receive motion from the crank 45 driven by the gearing 6, The other end of the walking beam is adapted to be connected to a pump rod in the usual way.

Actuation of the walking beam is facilitated by the use of a counterbalance. This from the walking beam close to the pitman 44 and anchored to the pitman at its lower end by a. link 47. Thus rod 46 is prevented from swinging relative to the pitman. Any desired number of weights 48 can be mounted on rod 46, these weights being removable and replaceable to properly counterbalance the walking beam.

It will be understood ofcourse that the walking beam is to be operated in the usual way but. importance is attached to the fact thatthe'entire apparatus is placed at one side of the well and does not straddle it or extend over it as ordinarily. While it is useful in pumping a well, it can also be employed for removing pumping equipment from the well. This can be done by extending a rope from the reel 28 over the pulley '23. A bailer can likewise be connected to this rope and used for removing sand and sediment from the well, it being possible to raise and lower the bailer at will by operating the reel in the usual way.

A rope mounted as hereto ore described can also be employed for drawing a pump provided, near one end, with a f Line from a well where such line iw sed in lieu of rods. I

By hingedly mounting the mast as described it can be held steady while being raised or lowered relative to the foundation. An important feature of the invention resides in the location of the reels. These are not carried by the mast but are supported by the braces 26. These braces not only serve to reinforce the mast but also constitute means for supporting the reels closer to the base than would otherwise be possible and the arrangement serves to practically eliminate danger of the apparatus turning over while being subjected to a load.

By mounting the walking beam so as to swing laterally as well as upwardly and downwardly it can be moved out of the way while a line on pulley 23 is in use. As the fulcrum of the walking beam is in vertical alinement with a portion of the beam 2, the counterbalance rod 46 with the weights 48 thereon acts to prevent the machine from overturning when subjected to excessive pull downwardly upon the working end of the walking beam;

The entire-apparatus is formed of metal so that it is thusr rendered very durable and eiiicient and capable of withstanding all of the rough usage to which apparatus of this kind is usually subjected.

By suspending the counterbalancing weights from one end of the walkin beam instead of piling them on the beam, t ere is no danger of the beam being tilted or twisted laterally under the excessive weight 4to which it is subjected. By connecting the rod 46 to the pitman the counterbalancing weights will be swung outwardly relative to the end of the walking beam while said end is being pulled downwardly, thereby to become more effective at the time when most needed in the operation of the mechanism.

What is claimed is:

1. In well drilling apparatus a base, a mast thereon, a member secured within the mast at a point over the base, a yoke mount- `ed for rotation upon said member about an upwardly extending axis, a walking beam mounted for up and down swinging movement within the yoke, an actuated member pivotally connected to and extending from one end of the walking beam, a pitman connected to the walking beam adjacent to its other end, a member pivotally connected to the walking beam adjacent to the pitman, a link connection between said member and the pitman for holding them constantly parallel, and a counter-balancing weight carried by said member, said walkin beam bein movable about the axis of tbe yoke to shift the pitman and the weight-carrying member laterally relative to the base.

2. In apparatus or' the class described a mast, a walking beam extending there through and mounted for up and down and for lateral swinging relative to mast, an actuating pitman connected tothe walking beam, a member suspended from and pivotally connected to the walking beam, a link connection between said member and the pitman for holding them constantly parallel, and a counter-balancing weight carried by the member.

In testimony that We claim the foregoing as our own, we have hereto aixed our signa,- tures.
